Air/water interfacial behaviour of phospholipid-porphyrin conjugates

A combination of techniques including synchrotron X-ray reflectivity have been used to assess the interfacial behaviour at the air/water interface of six newly synthesised Phospholipid-Porphyrin (Pl-Por) conjugates. This enabled to determine the impact of both porphyrin structure and linker length on the 2D phase behaviour of the conjugates and the formation of organised domains.

Phospholipid-porphyrin conjugates (Pl-Por) are considered as versatile building blocks for the development of light responsive nanomaterials thanks to their supramolecular assemblies, which enable multifunctional properties such as photothermal therapy, photodynamic therapy and photoacoustic imaging [1]. Pl-Por conjugates consist of porphyrin derivatives grafted to a lysophosphatidylcholine backbone. Owing to their structural similarities with phospholipids, Pl-Por conjugates can self-assemble into liposome-like structures [1-3]. Studying the interfacial behaviour of these compounds can offer a better understanding of

antisolvent volume that is required for perovskite manufacture. This introduces additional benefits in terms of large-scale processing and sustainability

two additional challenges that need to be addressed in order to enable the future integration of perovskite photovoltaics into industrial applications.
